Transmisor de Humedad y Temperatura para montaje en Ducto 220mm

The LPN-H is a complete relative humidity and temperature sensing module, with two loop powered 4~20mA output signals, representing 0~100%RH and 0~100ºC.

Two versions are available:
(i) Wall mount.
(ii) Duct mount.

Both versions come complete in an industry standard aluminium connection head.
The digital relative humidity sensor and temperature compensating sensor protrude from the head inside a protective cap. This cap allows air to circulate to the sensors.

The wide range of the humidity and temperature sensors offer long term reliability over a broad range of applications. The sensors resist contaminating vapours such as organic solvents, chlorine, and ammonia.

Calibration system for LPN-H series Humidity sensors:

The LPN-H-Ref system is designed to allow in situ calibration of LPN-H-W and LPN-H-D humidity transmitters. The LPN-H-Ref system consists of corrosion resistant stainless steel canisters containing humidity regulating salt solutions that replace the black protective filter on the sensor.

Important Note:
It is essential that the humidity sensor is mounted vertically with the filter at the bottom to prevent spillage.
